A/HRC/46/26 Figure 1: Responses to communications 2016–2020 Partially satisfactory 278 54% No response 186 36% Fully satisfactory 48 10% No response Fully satisfactory Partially satisfactory 58. A more detailed longitudinal overview of communications transmitted to States by calendar year (1 January 2017 – 31 October 2020) shows fluctuations in the number of official communications in parallel with fluctuations in available resources and the variable frequency of official travel, most prominently during the coronavirus disease (COVID-19) pandemic in 2020. Significantly, however, the relative proportions between the main levels of cooperation remained constant throughout the period under review, thus suggesting a stable pattern (see figure 2 below).

In conclusion over the long term, more than one third (36 per cent) of official communications transmitted to States by the mandate holder do not receive any response whatsoever (“no cooperation”); 54 per cent receive responses that are otherwise unsatisfactory (“partial cooperation”); while only 10 per cent receive a fully satisfactory response that adequately addresses the allegations transmitted of torture or ill-treatment as requested or recommended by the mandate holder (“full cooperation”). 2.
